IMPROVEMENT IN LOOMS.

Specification forming part of Letters Patent No. 120,510, dated October31, 1871.

To all whom it may concern:

Be it known that I, WILLIAM V. GEE, of Philadelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented a new and valuableImprovement in Looms; and I do hereby declare that the following is afull, clear, and exact description of the construction and operation ofthe same, reference being had to the anneXed drawing making a part ofthis specification, and to the letters and gures of reference markedthereon.

Figure 1 of the drawing is a front view of my invention. Fig. 2 is ahorizontal section of the same. Fig. 3 is a vertical section.

This invention has relation to looms 5 and it consists in theapplication of certain improvements by means of which the shuttle orweftcarrying finger is required to traval only onehalf the usualdistance required, thereby saving time and increasing the amount of workpro` duced in a given period.

In the accompanying drawing, illustrating my invention, A A representthe ends of a loomframe, A being the driving end. B is a transverseshaft, holding the eccentrics C C', which operate the batten-frame D,and an eccentric, E, for controlling the operation of a device thefunction of which will be hereinafter detailed. On the driving end ofthe shaft B is a crank or driving-wheel, B', and a grooved cam, B, onwhich travels a stud, b, projecting from an arm, b', pivoted to abracket, which extends from the driving end of the loom-frame. The arm bis connected by a link, E', with a bar, E, which is thereby operated torise and fall through a slotted bracket, E, secured to and projectingfrom the end of the batten-frame D. F indicates a horizontal barsupported on the battenframe; F', a bevel-edged horizontal race, uponwhich the finger and hook F F, respectively, travel reciprocally, beingeach provided with dovetailed guides ff to support them on the race F;Gr G, cleats secured to the guide portions of the iinger and hook, andformed with eyes, by means of which a continuous cord, g, is attachedthereto. This cord passes over a pulley-wheel, G', journaled at one endof the race, and has both of its ends secured to a pulley-wheel, G,journaled at the opposite end.

The reciprocating rotary motion of the wheel G operates the finger andhook, which alternately come together and separate, the end of the hookin the first instance entering the tubular portion of the finger andthere seizing the weft-yarn, which the finger has carried with it fromthe edge of the warp half the distance, and afteiwi'ard drawing it tothe opposite edge. Having reached the latter point the yarn is caught bya hook, Il, on t-he end of an oscillating lever, Hf, constructed withjaws H, between which the eccentric E, previously referred to, rotatesand oscillates said lever and the hook which it holds. A iinger, lz.,properly attached to this hook is made to close the latter after it hastaken hold of a yarn, and until it has drawn the same forward somedistance, when it opens automatically, and falling back, allows the yarnto pass over it, the hook at the same time reversing its travel for thepurpose of seizing the next stretch of yarn, and so on, the looped endof each succeeding stretch being taken as a link to form thelchainselvage of the 1naterial)which is being woven.

I denotes a pulleywheel, journaled on the same shaft with the wheel G. Acord,1, which passes around the wheel I is connected by its ends to astud, i', projecting from the upper end ofthe bar E, and to the pinwhich connects together said bar and the link E. Thus, when the bar E ismade to rise and fall through the medium of the cam b', the cord irotates the wheel I, and motion is thereby communicated to the finger Fand hook F to operate them, as before described.

J represents the mai1s,having eyes, through which the weft-yarns are fedfrom the bobbins K to the finger F. These mails are hung on a transversebar behind the hatten-frame, and have cords connecting them with aJacquard attachment, which, being in general use, is not shown in thedrawing.

The mails are operated in the usual manner, each holding adiierent-colored va-rn, which may be brought into requisition whendesired.

Having described my invention, I claim- The bar E, cam B, cord i, linkE', arm b', and pulley I, in combination with the cord g, pulleys G Gfinger F, and hook F', arranged to operate substantially as described.

In testimony that'I claim the above I have hereunto subscribed my namein the presence of two witnesses.
